Nope

wickens and soderstrom

That’s the stuff matey! Anyone tried it?.

Not going to bother, 18 quid for 2 tyres worth, granted its supposed to last ages, but I like to swap tyres about.

Back to Stans.

I find the effetto stuff mentioned above very good, better than Stans in fact.

Using one of the ones PX do – comes in a massive bottle with a dual cap that doses.
Done half a dozen tyres and doesn’t seem as if I’ve touched it yet.
Was about £7

Take that back!! £3 now HERE

Stanleys ?
